摘要
转动惯量作为一个重要的工程参数，如何准确地测量转动惯量在工程上具有重大意义。
本文针对ZME-1综合力学实验台“三线摆”法测转动惯量测量实验，设计出一套能够较精确的测量物体转动惯量的实验辅助装置。该装置采用非接触测量方式，可以方便、快捷、准确的获取三线摆盘转动的周期信号。经在实验室检验该转动惯量测量装置，能准确稳定的采集到周期旋转信号。

ABSTRACT
The moment of inertia as an important engineering parameters, how to measure the moment of inertia accurately has    a magnificent significance in the project.
This thesis based on the trilinear pendulum method to measure the moment of inertia at the ZME-1 com
prehensive mechanical bench. Designing a more accurate system to measure the moment of inertia, the system can display real-time swing cycle, automatically calculates the moment of inertia data. Designed non-contact measurement can be convenient, fast, accurate estimates of three-wire pendulum rotation cycle. The moment of inertia measure equipment has been tested in the laboratory that can collect the periodic turn signal accurately and stably.
Key words : Moment of Inertia, Trilinear Pendulum, Measurement System, Assistive Devices, Non-contact measurement
